RMx4 combines a four-channel field mixer with a four-channel headphone amplifier. After all, what good is a field mixer if you don’t have a flexible monitoring capability for the whole crew?

A soft limiter prevents overdriving the full-duplex headset interface, while the master XLR and 3.5 mm outputs are pre-limiter (full range). Line level cue input to the headphones make RMx4 a perfect companion to your codec or recorder.

3.5 mm send and receive jacks for recording or playing back recorded material. Separate headphone level and source selection controls for each headphone output. Monitor just the clean mixer output, or the Cue input plus the mix.

Switchable 48V Phantom Power on each mic input. Powered by 1 or 2 hot-swappable 9V batteries that automatically kick in if AC power goes down. Low noise, low power ICs are used throughout to preserve battery life. The 100-240 VAC desktop style power supply (included) overrides the battery power only when the supply is actually providing power.

RMx4 is designed for news and sports remotes. Use it as a front-end mixer for your POTS, ISDN, IP or smart phone codec. XLR out, ¼” return to headphones.

RMx4 is designed for ENG, Sports, and interviews, with four ¼” headphone outputs. 3.5 mm TRRS provides 2-way IFB audio from your cell phone or notebook.
